WILLIAM E. PINCKNEY, OF PORTLAND, OREGON.

VACUUM CUP FOR WASHING MACHINES.

Application filed November 10, 1924; Serial No. 748,920.

T 0 all whom it may concern:

Be it hereby known that I, WILLIAM E. PINGKNEY, a citizen of the United States, and a resident of Portland, in the county of Multnomah and State of Oregon, have invented new and useful Vacuum Cups for l/Vashing Machines, of which the following is a specification.

This invention relates particularly to vacuum cups for washing machines.

The object of my invention is to provide an exceedingly simple and elficient type of pounder which can be employed in square or rectangular containers without the employment of ratcheting devices or means for shifting the position of the clothes.

The second object is to so construct the cups that practically every portion of the container will be within reach of the pounding action of the cups.

The third object is the provision of a type of pounder especially adaptable for use in connection with the washin machine described in my companion app ication, Serial No. 748,921.

I accomplish these results in the manner set forth in the following specification and illustrated in the accompanying drawing, in which:

Figure 1 is a horizontal section through the water container showing the device in plan. Figure 2 is a vertical section taken along the line 2-2 in Figure 1. Figure 3 is a vertical section taken along the line 33 in Figure 1.

Similar numbers of reference refer to the same parts throughout the several views.

Referring in detail to the drawing, in order to illustrate the device I have indicated the lower portion of a rectangular water container consisting of the bottom 10 and sides 11 and 12. Mounted on the bottom 10 is a tubular guide 13 in which is slidably mounted a plunger 14 across whose upper end 15 is secured the cross arms 16 and 17 to which are attached the T cups 18 and the longitudinal cups 19 respectively. The short rods 20 are employed to fasten the cups to the arms.

It will be understood that in operating 5 the device, clothes are inserted into same and the plunger 14 reciprocated in the usual manner by an actuating device (not shown). By shaping the individual cups, as illustrated, sufiicient area remains between the cups for the displacement of the water and clothes and for. the suds to form.

It will be seen that by this construction it is unnecessary to provide special devices or mechanisms for bringing all of the clothes under the action of the pounders, and that greater efficiency is secured because each article of clothing is subjected to the pounding action a greater average length of time than would otherwise be possible.

I am aware that many forms of vacuum cup plunger washers have been constructed in the past, I therefore do not cover same broadly, but I do intend to cover such forms and modifications as fall fairly within the appended claim, a special reference being made to their employment in connection with a rectangular receptacle.

I claim:

The combination of a rectangular water container having a vertical plunger mounted near the middle of its bottom; a pair of crossed arms attached to the upper end of said plunger; a pair of T-shaped cups at the opposite ends of one pair of arms; and a pair of longitudinal cups 011 the opposite ends of the remaining pair of arms said longitudinal cups occupying space between said T-shaped cups, all of said cups occupying the major portion of the area of said water container.
